Abstract
In this work, a novel photo-alignment material, poly(cinnamolyethyl methacr
ylate) (PCEMA), was synthesized by photo-dimerization. We investigated the
electro-optical characteristics of twisted nematic (TN)-liquid crystal disp
lays (LCDs) photo-aligned with linearly polarized UV light irradiation at n
ormal direction on the PCEMA surfaces. Excellent voltage-transmittance char
acteristics were observed. The threshold voltage of the photo-aligned TN-LC
D decreases with increasing UV irradiation time. Additionally, response tim
es are almost the same as for a rubbing-aligned TN-LCD.
